INTRODUCTIONSurveillance system are inevitable which uses more than one cameras today.
Here we introduces a new system for surveillance that has only PIR sensor, MCU and a smartphone .
WHAT IS INTELLIEGNT SURVEILLANCE SYSTEM?
MOTION DETECTED
VIDEO CAPTURED
HOW DOES IT WORK
SYSTEM ARCHITECTURE
HARDWARE MODEL
PIR SENSORS
• PIR sensors works on pyroelectricity principle.• PIR sensors consists of a pyroelectric element.• The PIR sensor detects the infrared radiation emitted
or reflected from an object.
PIR SENSORS
PIR SENSORS• PIR sensors can be operates on two voltage
levels(3.3v and 5v)• The PIR sensor can detect motions up to 7m
vicinity but its direction probability is high within 4m.
PIR SENSORS
SENSOR INPUT LOCKING SYSTEM
• Continuous stream of high and low signal is send to MCU when there is motion or not from PIR output.
• To get an exact time slot of the motion a simple input locking mechanism is implemented using a lock variable.
SENSOR INPUT LOCKING SYSTEM• Output state of the sensor changes from LOW
to HIGH then the lock variable is made TRUE else it is FALSE.
CLOUD STORAGE
Cloud storage is a model of data storage where the digital data is stored in logical pools and the physical environment is typically owned and managed by a hosting company.
IMPLEMENTATION
ADVANTAGES• Smartphone is used as the eye of the system.• Reduces lot of energy.• Whole design is compact and easily
mountable.• Cloud storage solves the storage issues.
APPLICATIONS• Defence purposes.• Home security systems.• Protection purposes.
CONCLUSION• A new method for intelligent surveillance utilizing the
capabilities of a smartphone along with PIR sensor.• The energy usage is reduced by activating the
camera only when the movement is detected by PIR sensor.
• As a future work, the efficiency of our design can be further improved by adding more sensors to it.
